Using the PC100 Ethernet Adaptor with
Windows Firewall (XP/SP2).
This will explain how to use the PC 100 Ethernet adaptor on PCs
running Windows XP with Service Pack2 (XP/SP2). One of the new
components included in SP2 is a Windows Firewall. Unless setup
correctl , the Firewall will prevent certain features of PC100
Ethernet adaptor software from operating properl .
Using auto-discovery access mode of DS Manager with
Windows Firewall
One difference ou will immediatel notice after XP2 is installed
and the Firewall is enabled is that the DS Manager can no longer
find local Device Servers in the auto-discover access mode
(address book mode continues to operate properl ). You can find
an explanation on wh this is happening later in this Note.

15
Once ou run the DS Manager (or click Refresh in the auto-
discover mode), and provided that our Firewall is using default
configuration, ou will get this warning message:
This message means that Windows Firewall has detected certain
network activit that is currentl not allowed. Application name is
"Run DLL as an App" and, believe it or not, this is how Windows
sees the DS Manager ( es, DS Manager is a "DLL" but Windows
should be smart enough to understand its "real name".... alas, it
isn't that smart). Click Unblock and the DS Manager will be able to
auto-discover local Device Servers again.
If, when ou run the DS Manager (click Refresh), the warning is
not displa ed (and the DS Manager is still unable to find Device
Servers) then this ma be because the Firewall is not allowing
"exceptions" and/or firewall notifications are not enabled.
Run the Firewall (Start-- Control Panel-- Windows Firewall) and
make sure that Don't allow exceptions checkbox is unchecked
(clear):

16
Next, click on the Exceptions tab and make sure that Display a
notification when Windows Firewall blocks a program checkbox is
checked:

17
After ou "unblock" the DS Manager the Firewall puts it into the
list of "exceptions" i.e. programs whose traffic is allowed to pass
through the Firewall:

18
Manual way of making the auto-discovery mode work
Same result can be achieved b telling the Firewall which port on
